Patent JP-H0455788-A (JP)
Title: Laser ranging device
Inventor: HATSUDA YOSHIO
IPC: G01S17/08
Filed: 1990-06-26
Abstract: PURPOSE:To suppress error in distance measurement by filtering received signal and letting pass only the frequency spectrum of transmission pulse light. CONSTITUTION:A Q-switch pulse laser oscillator 1 outputs pulse laser light, a light detector 3 converts a part of the laser light to a signal 20 to supply to a comparison output circuit 12, and the circuit 12 converts it to comparison output 21. Most of the output light from the oscillator 1 irradiates a distance measurement target 5a after passing through a transmission optical system 4 and becoming a narrow beam laser light 6. The scattered light propagates in the space, condensed in a condenser 7, and supplied to a receiver system 8. The receiver system 8 lets pass only pulse laser light selectively to add to BPF 17. And the BPF 17 lets pass only frequency spectrum component of the transmission laser pulse, cuts long pulse component and add to a comparison output circuit 13 to convert to comparison output 22. And a distance measurement counter 9 counts outputs 21, 22 to measure the reciprocation time of the laser light. With this method, distance measurement free from the influence of long pulse formed by scattering around the target is possible.

Title: Control circuit for dc motor
Inventor: FUKUSHIMA YASUHIRO
IPC: H02P7/288
Filed: 1979-12-21
Abstract: PURPOSE:To form a control circuit which is characterized by the stable motor control at a low speed rotation and easy manegement of amplification of a motor driving portion by detecting the balance and unbalance of a bridge by a voltage comparator, and obtaining a digital signal of a 0 or a 1. CONSTITUTION:The bridge is formed by the DC motor 1, resistors 4, 5, and 6, and a reference voltage generatos 2. The comparator 3 compares the potentials at  (a) and (b) and sends out a digital signal of a 0 or a 1. The output thereof is converted to an analog signal by a low-pass filter formed by resistors 7 and 9 and a capacitor 8, and controls a motor driving amplifier which is connected as a Darlington circuit by transistors 10 and 11. Therefore, even though the amplification factors of  the transistors are slightly changed at a low rpm, the change is absorbed into the  output pulses of the comparator by the pulse width modulation, the rpm can be selected in the broad range.

Title: Semiconductor element
Inventor: SHIMADA KAZUYUKI

Abstract: PURPOSE:To obtain sure connection by forming the electrode parts of a semiconductor element as Au bumps and providing a thermoadhesive sheet formed by dispersing conductive fillers having elasticity into a high-polymer material having thermoadhesiveness on a semiconductor element forming surface. CONSTITUTION:The bumps formed by electroplating of Au are provided on the semiconductor element and further, the thermoadhesive sheet formed by dispersing the conductive films is laminated over the entire surface of the semiconductor element. An LSI chip is, therefore, electrically connected without metallizing ITO. Namely, anisotropy is exhibited by forming the thermoadhesive sheet dispersed with the conductive fillers on the Au bumps and the connection onto the ITO is executed by thermocompression bonding. The electrical connection is thereby more surely executed.

Title: Rotary type punching device
Inventor: SATO TAKUYA
IPC: B26F1/08
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To enhance the punching accuracy by preventing generation of an error between the paper sheet feeding speed and the linear velocity of a punch and die. SOLUTION: At a certain spacing fore and aft, photo-interrupters 32, 33 for sensing a sheet of paper are installed in a front sheet guide 31 positioned downstream of a sheet feeder unit 15. A control part calculates the sheet feeding speed from the time difference between the sheet sensing signals given by the photo-interrupters 32, 33 and the distance between them. The control part feeds back the deviation of the actual sheet feeding speed from its target value to a sheet feed servo circuit and puts the sheet feeding speed identical to the linear velocity of a punch.

Title: Optical communication system
Inventor: SUZUKI NORITO
IPC: H04B10/2513
Filed: 1979-12-23
Abstract: PURPOSE:To enable multiplex communication by waveform discrimination by converging many oscillation waves having different wavelength and sending them to the same optical fiber while minimizing signal distortion on an optical fiber transmission line, by providing a means of fixing completely the oscillation wavelength of a semiconductor laser. CONSTITUTION:Although the line concentration of an even-interval concave lattice forms a loran circle, that of uneven-interval concave lattice 3 makes nearly straight line 2 as shown in the figure. When semiconductor lasers 1 are only installed at proper position on straight line 2, the oscillation wavelengths of lasers 1 are fixed by the cavity formed of grating 3, obtaining wavelength lambda1=2dsintheta1, where (d) is a representative lattice constant and theta1 is an incident angle to lattice 3. Then, oscillation light is extracted by the reflected light of lattice 3 and converged into point 0 by lattice 4 before being sent to the same optical fiber.

IPC: H02J7/00
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a solar light generation facility equipped housing, wherein the demand factor for the solar light generation facility is increased and thereby the redemption period of the initial cost is shortened. SOLUTION: This housing is provided with a solar light generation means 10, including a solar battery 11 which generates power with solar light and a distribution board 3 for distributing power to various electric equipment.

Abstract: PURPOSE:To detect a leader tape part no matter when it is the recording operation time or the reproducing operation time by making it possible that the leader tape part is detected even if a magnetic signal is leaked from a magnetic recording head to a magnetic reproducing head at the magnetic recording operation time. CONSTITUTION:A leak signal eliminating circuit 19 synthesizes and subtracts a leak signal 30, which is detected by a magnetic reproducing head 2b at the magnetic recording operation time, and a leak signal conjectured through a recording signal detecting circuit 8 and generates a minimum output voltage for a leader tape.

By this operation of the circuit 20, the leader tape part can be detected by a head 2b at the magnetic recording operation time as well as the magnetic reproducing operation time.
